| Repeat the experiment using the PMOS device. The connections are similar and as shown on figure 2 below. You may notice that the polarity of the scope inputs has been reversed in this case. This is so that the direction of the voltage and currents on the scope screen will be similar to the NMOS case. The Source of M<sub>1</sub> is connected to Vp. Connect scope input 2+ and scope input 1- to the gate - drain node of M1. Be sure that the power supply (Vp) is turned off while you build your circuit. Once you are sure all your connections are correct then turn on the supplies. | Repeat the experiment using the PMOS device. The connections are similar and as shown on figure 4 below.
